These best practices show how customers can lower the migration risk of moving from a physical environment running HP-UX to Vblock platforms running Red Hat Linux in a virtualized environment. Traditional infrastructure practices recommend sizing for the worst case, which is an inefficient approach that adds to business risk. With Vblock platforms, customers can size for the optimum size and take advantage of the dynamic scalability for SAP to support the worst-case scenarios. This paper provides guidance and testing results from a proof of concept (POC) performed for a large semiconductor equipment manufacturing company. The company‟s SAP landscape includes the following modules: ERP, SCM, SRM, BI, PI, EP. The tests involved migration and performance of two core SAP modules, ERP SCM and LiveCache. Vblock Series 700 model MX was used as the target environment for this migration. Business Case Virtualization has rapidly gained momentum in enterprise IT environments because organizations are looking for ways to control escalating hardware costs, and to optimize their use of energy and resources while improving business continuity. Virtualization of complex SAP applications can reduce costs and increase speed and resilience. Virtualization also permits faster data analysis and expands data analysis capabilities. Key Results Key results demonstrate that once deployed on the Vblock platforms, SAP showed performance improvement well over the incumbent hardware. The following lists the key findings:   Performance improvement of 50% or more when running SAP on the Vblock platforms compared with a large semiconductor equipment manufacturer  ‟s  environment.    50% less hardware was used compared to the customer‟s environment     Low migration risk of moving from an HP-UX based physical environment to a Vblock platform virtualized environment   Fast recovery of failed application and database server blades with UIM and Cisco UCS service profiles   Increase scalability to dynamically add resources   High availability and live migration demonstrated though vMotion    © 2011 VCE Company, LLC.

Vblock platform shows high performance compared to HP-UX Scope This document provides best practices for the OS/DB migration of SAP from HP Integrity Itanium   servers running PA-RISC/HP-UX to the Vblock Infrastructure Platforms running x86/Red Hat Linux. Objectives The objectives of the SAP OS/DB Migration from HP-UX Platform to Vblock Platforms  best practices paper are to: 1. Show how best practices were utilized to successfully complete the SAP migration to Vblock 700 and explain how customers can use the same best practices to perform their migration. The approaches used for sizing, application layout, storage layout, and the SAP migration procedure are all based on best practices. 2. Provide the collected testing/monitoring results data associated with the migration, and also demonstrate running the applications on the Vblock 700. 3. Compare performance of a Vblock platform to a customer environment.  Audience This paper is intended for Vblock platform customers, SAP administrators and architects, and technical engineering staff, managers, IT planners, administrators, and other IT professionals who are evaluating, acquiring, managing, operating, or deploying SAP in a virtualized data center environment.
